The purpose of the present study is twofold: one is to understand secondary mathematics teachers' capacity to sort out given tasks based on Stein & Smith(1998)'s Cognitive Demands of Mathematical Task Framework; the second is to examine how the teachers assess the levels of cognitive demand indicated in students' reponses and how they modify the tasks to elicit the students' higher levels of cognitive activity. The analysis of 45 teachers' responses to the survey indicates that the teachers, in general, could select appropriate tasks for the given goal of the lessons but some made the decision merely by their appearances. Even though the teachers chose a particular level with different reasons amongst each other, most teachers could correctly evaluate the levels of cognitive demand of the students' responses. Finally, teachers could pose cognitively demanding tasks using various methods, but a number of them felt challenged in creating word problems that were realistic and aligned with curriculum.

This study analyzed the effects of ICT technical characteristics of agricultural industry on smart farm entrepreneurial intention by using smart farm effort expectation and smart farm acceptance intention as mediators for smart farm pre-founders. Sub-variables of the technical characteristics of agricultural industry ICT were classified into availability, economics, data convergence and scalability. 349 questionnaires collected from pre-founders living in the country were used for empirical analysis. SPSS v22.0 and Process macro v3.4 were used to analyze the data based on serial multiple mediation model. First, economics and scalability had a positive (+) effect on start-up intention. Second, availability, economics and scalability had a significant effect on effort expectation. Third, effort expectation had a significant positive effect on acceptance intention. Fourth, acceptance intention had a significant positive effect on start-up intention. Fifth, the indirect effects of economics on start-up intention were all significant through effort expectation, through acceptance intention and through both effort expectation and acceptance intention. Sixth, the indirect effect of data convergence on start-up intention was significant through acceptance intention. Seventh, the indirect effect of scalability on start-up intention was significant through effort expectation and through both effort expectation and acceptance intention. As a follow-up study, it is necessary to study for the mediating variables other than mediators introduced in the study or the moderated mediation analysis through the conditional process model in which the moderating variable is introduced.

The software reliability have to be improved as one major method to enhance the quality of developed software, and its defect is detected and modified through testing as a direct way to meet the purpose before releasing. Once its reliability grows up to the target and it is released to public. there nay be operational reliability problem. The operational software reliability trend nay be different depending on the condition whether it is universal or dedicated. And its reliability estimation is changed based on the condition if it follows uniform testing efforts or Weibull testing efforts. I study the operational reliability trend of dedicated software, applying two case testing efforts for the released item.

Enterprise Architecture (EA) is known as a means to solve IT management problems. In 2005, the South Korean government introduced it and required each agency to develop a variety of architectural products. Such an early-stage EA effort turned out to be not very effective because those products were hardly of use for pan-government IT governance. Realizing these problems, the Lee Myung Bak government has decided to change its direction so that EA products would also be utilized at pan-government IT decisionmaking. After reviewing the early stage of EA effort, we in this study describe such a transition. Future directions of EA efforts are also discussed at the end.

Background : Sex specific cross sectional reference values for the lung function indices usually employ a linear model with a term for age and height. The purpose of this study was to determine the effects of the body mass index (BMI), the fat percentage of the body mass and the fat-free mass index (FFMI) on the forced expiratory volume curve. Methods : Between January 2000 and December 2001, a total of 300 subjects, 150 men and 150 women (mean age : $45{\pm}13$ years), with a normal lung function were enrolled in the study sample. This study measured the $FEV_1$, FVC and $FEF_{25-75%}$ from the forced expiratory volume curve by a spirometer and the body composition by a bioelectrical impedance method in all subjects. Multiple regression analysis was used in order to examine the effects of the body composition on the parameters derived from the forced expiratory volume curve. Results : After adjusting for age, the BMI and Fat percentage improved the descriptions of the FVC (p<0.05, $r^2=0.491$) and $FEV_1$ (p<0.05, $r^2=0.654$) in women. In contrast, the FFMI contributed significantly to the FVC (p<0.05, $r^2=0.432$) and $FEV_1$ (p<0.05, $r^2=0.567$) in men. The $FEF_{25-75%}$ correlated with the fat percentage in women (p<0.05, $r^2=0.337$). Conclusion : These results suggest that the BMI, the fat percentage and the FFMI are significant determinants of the forced expiratory volume curve. The plmonary function test, when considering the BMI, the fat percentage and the FFMI, might be useful in clinical applications.

1968년 ARPA 네트워크의 출현 이후 음성 서비스 위주의 네트워크와 데이터 서비스 위주의 네트워크는 서로의 서비스를 수용하기 위해 노력해왔다. 음성 기반의 네트워크에서 데이터를 수용하기 위한 노력은 ‘꿈의 망’으로 그친 ISDN(Integrated Services Digital Network)으로 나타났고, 데이터 기반의 네트워크에서 음성을 수용하기 위한 노력은 보편적인 비연결형 데이터 서비스와는 대비되는 B-ISDN(Broadband-ISDN)으로 나타났다. 이후 다시 B-ISDN은 IP 서비스의 수용을 위해 ATM 교환기를 MPLS(Multi Protocol Label Switching) 교환기로 대치하여 보완하고 있지만, VoIP(Voice over IP)등 음성서비스의 제공에는 아직 완전한 해법이 제시되지 못하고 있다.(중략)

근대 사회의 보편적인 건축의 언어를 창출하려던 모더니즘의 신화가 무너지고 난 후에, 새로운 보편적 건축양식을 찾아보려는 노력은 현재까지 계속되어오고 있으나 현대건축에서 공유할 수 있는 보편적 건축어휘는 부재한 상황이다. 현대의 건축가들은 각자의 건축적 언어체계를 만들어내려는 노력과 더불어 여러 방면의 건축적 실험을 통해 새로운 건축의 규범을 정의하려는 노력에도 경주하고 있다. (중략)

가능성이란 항상 삶을 살아가게 하는 원동력이 되어주며, 이를 잃어버린 생활은 원동력이 되어주며, 이를 잃어버린 생활은 특별한 목표가 없는 부평초같은 의미없는 삶이 되기도 한다. 가능성을 현실로 바꾸어 나가기 위해서는 끊임없는 노력이 요구되어지며, 어떤 경우에는 전혀 생각지 못한 암벽이 앞을 가로막기도 한다. 힘들기는 하지만 가능성을 실현시키기 위해 노력하는 생활, 이것이 바로 기쁨과 행복을 생산해 내는 '삶의 원천'일 것이다. 최근 4-5년동안에 타 지역의 도시개발에 따른 양돈 농가수의 감소와는 반대로 자연적 여건의 도움으로 새로이 양돈농가가 늘고 있는 대한양돈협회 함양지부는 함양의 양돈발전 가능성을 크게 인지하고 더욱 빠른 시일내에 그 가능성을 현실로 만들기 위해 부단히 노력하고 있는 지부이다.
